What you mention was covered by the 2nd part of my "b" item. If the
host is shared among multiple domains [and you want it to answer for
some, but not all, of those domains], have them/it refuse email
directed at recipients of that domain [that you don't want to receive
email]. Pretty easy to do with filter_recipient.
